Why is the robots.txt AI Crawler Check important?

    
Many websites unknowingly block AI crawlers like GPTBot (ChatGPT), ClaudeBot (Anthropic) or Google-Extended (Gemini). This can cause your brand to be absent from AI-generated answers.

    
robots.txt controls access – not just for Google, but also for new AI systems. Every blocked crawler means less visibility in a growing channel.

    
This check tests 13 relevant AI crawlers and instantly shows which are blocked. Combined with the AI Visibility Check and the Schema.org Checker you get a complete picture of your AI visibility.

Common robots.txt Mistakes with AI Crawlers


Many websites accidentally block AI crawlers through overly restrictive robots.txt rules. Common mistakes include a blanket Disallow: / for all user agents that also affects GPTBot and ClaudeBot, or missing explicit Allow rules for AI bots.


Which AI Crawlers Exist?


Our check analyzes 13 AI crawlers: GPTBot and ChatGPT-User from OpenAI, ClaudeBot from Anthropic, PerplexityBot, Google-Extended for Gemini, Applebot-Extended for Apple Intelligence, Bytespider from ByteDance, and more. Each crawler has its own user-agent string that can be specifically controlled in robots.txt.

What does the robots.txt AI Check analyze?

    
The robots.txt AI Crawler Check analyzes your robots.txt file and shows which AI crawlers have access to your website. It checks GPTBot (ChatGPT), ClaudeBot (Anthropic), PerplexityBot, Google-Extended and other AI agents.

    
Why do many websites block AI crawlers?

    
Many standard robots.txt templates accidentally block AI crawlers. This means ChatGPT and Claude cannot read your products and content – and consequently cannot recommend them. This check shows you at a glance which crawlers are blocked and how to unblock them.

    
Optimal robots.txt for AI Visibility

    
For maximum AI visibility, you should explicitly allow GPTBot, ClaudeBot, PerplexityBot and Google-Extended in your robots.txt. Our check automatically generates the optimal configuration – copy, paste, done.

The Most Important AI Crawlers at a Glance

    
GPTBot (OpenAI/ChatGPT) is the most widespread AI crawler. It indexes web pages so ChatGPT can use current information in its answers. User-Agent: GPTBot/1.0

    
ClaudeBot (Anthropic) crawls for Claude. If you want Claude to recommend your products, ClaudeBot needs access to your website. User-Agent: ClaudeBot/1.0

    
PerplexityBot uses your content for real-time search results. Google-Extended controls whether Google can use your content for Gemini and AI Overviews. Both should be allowed for maximum GEO impact.
